Machine Operation
CONTROLS/PROGRAMMING/SETTINGS
After the unit is connected to power it will automatically
begin operating. With the doors closed, the temperature of
the cabinet should reach 36°F to 40°F (2°C to 4°C) in about
one hour.
A thermostat located in the evaporator housing on interior
rear of the unit, controls the temperature in the unit. The
factory setting for the control is 4 and maintains about 38°F
(3°C) in the box. Set toward 1 for higher temperatures and
toward 7 for lower temperatures.
Refrigerators defrost automatically with every cycle of the
compressor. The water generated is routed to a pan on the
rear of the unit and is evaporated by the heat given off by
the compressor.
NOTE: During normal operation the evaporator fan may
cycle and/or pulse independently of the compressor.
